I/O processor
Understand the Problem
The question refers to an I/O processor, which is a component of a computer system that manages input and output operations. It plays a critical role in handling data transfer between the central processing unit (CPU) and peripheral devices.
Answer
An I/O processor manages data transfer between peripherals and the CPU, executing I/O instructions and storing data.
An Input/Output (I/O) processor is a specialized processor responsible for managing data transfer between computer peripherals and the central processing unit (CPU). It performs tasks like loading, storing data in memory, and handling I/O instructions, allowing the CPU to focus on executing core tasks.
Answer for screen readers
An Input/Output (I/O) processor is a specialized processor responsible for managing data transfer between computer peripherals and the central processing unit (CPU). It performs tasks like loading, storing data in memory, and handling I/O instructions, allowing the CPU to focus on executing core tasks.
More Information
The I/O processor handles data transfer responsibilities, which offloads these tasks from the CPU, improving overall system efficiency and allowing the CPU to focus on processing core instructions.
Tips
A common mistake is confusing the I/O processor with a DMA controller; while related, they have distinct roles and functionalities.
